ARTHUR BATES AND ARTHUR OASELTON, 0F LEICESTER, ENGLAND, ASSIGNORS TOUNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORA- TIONOF NEW JERSEY.

To all whom it may concern:

Be it known that we, ARTHUR BATES and .ARTHUR CASELTON, subjects of theKing of England, residing at Leicester, Leicestershire, England, haveinvented certain Improvements in Lasting-Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference'characters on the drawings indicatinglike parts in the several figures.

This invention relates to machines for use in the manufacture of bootsand shoes and is herein shown as embodied in a lastin machine of thehand method type, although it will be understood that many features ofthe invention are susceptible of wide application.

This invention will be explained in connection with a single pincerlasting machine of the general type shown in United States LettersPatent No. 584,74, and particularly with reference to a machine ofthistype having a plurality of fastening inserting devices such, forexample, as that shown and described in United States Letters Patent No.1,007,051, granted October 13, 1911, on application of Arthur Bates.

In machines embodying the Bates invention there are provided two tackdrivers which are carried on separate driver bars located side by sideon a single driver bar carrier, the carrier being adapted to be swungabout a pivot for moving the drivers into and out of tack drivingposition. Means is provided for raising the driver bar carrier, and asingle actuating spring forces the carrier downwardly to drive thetacks, the tack drivers operating simultaneously to drive separate tacksinto the work. In ma chines of'this type there is provided means forpreparing the work for the fastening operation such, for example, asmechanism for plaiting the upper or a reciprocating member for wipingthe upper over the shoe bottom, for example, a tack block. This priormachine is also provided with a thick edge gage which is adapted to bebrought into operation when required, usually when the plaitingmechanism is in operation, and usually has also a thin edge gage,located above the thick edge gage, which remains in place whether thethick edge gage is in operative position or not. A lever, usually abellcrank lever, is provided for moving the Specification of LettersPatent. 7

edge gage into and out of operative position. At certain times, forexample when plaiting takes place at the toe, it has been founddisadvantageous to have both of the drivers continuously in operation asthey are in this prior construction. In this prior machine the operationof one of the drivers is rendered ineffective to drive tacks by stoppingthe passage of tacks from the raceway and since both drivers arecontinuously in operation, when the supply of tacks to one of thedrivers is discontinued to prevent that driver from inserting thefastenings'into the work the driver will, by this continued operationdrive the tack already in the holder beneath it and when it is againdesired to drive two tacks it will be necessary to wait through onecycle of the machine until the tack supply device has filled the tackholder beneath the driver before two tacks can again be drivensimultaneously.

One of the features of the present invention consists in a plurality ofdrivers arranged to drive adjacent tacks, and means for suspending theoperation of one of a plurality of drivers while another drivercontinues in operation and while the holder cooperating with thesuspended driver retains a tack ready for insertion until the operationof the suspended driver is resumed. w 0

Another feature of the present invention consists in a plurality ofindependently actuated fastening insertingdevices for in' serting attimes a plurality of fastenings, with other means for operating upon thesame portion of the work as is operated upon by the fastening insertingdevices, and a controller for said other means which is constructed andarranged to suspend the operation of one of said fastening insertingdevices upon movement of said means. In the illustrated embodiment ofthe invention, which is a lasting machine, theother means referred to isemployed at the more diflicult part of the shoe to prepare the work forthe fastening operation and the controlling means is arranged to suspendthe operation of one of the fastening inserting devices when the saidother means for operating upon the same portion of the work is renderedoperative. The other means may comprise an upper plaiting mechanismincluding a plaiter controller which may occupy either oftwo positions.In the present embodiment of the invention there is provided aconnection from the plaiter controller to the driver and this connectionrenders the driver inoperative to insert tacks when the controlleroccupies one of its positions. in the construction shown, a driverdetent is provided which is normally connected with the driver and whichis disconnected from the driver di ring movement of the driver over theshoe, and the connection referred to extends between the plaitercontroller and the detent and allows the connection between the driverand detent to continue when the controller occupies the position toproduce upper plaiting movements and effects a disconnecti when thecontroller occupies another position.

Another important feature of the invention is found in the tack driver,in combination with a shoe gage which is movable between two positions.and a tack holder movable over the shoe bottom to present tack inposition to he acted upon by the driver. together with connections fromthe edge gage to the driver which renders the driver operative when theedge gage occupies one of its positions. In the construction shown. thedriver detent above mentioned is normally corniccted with the driver andthe connection between the edge gage and the driver is constructed andarranged to prevent such disconnection when the edge gage occupies oneof its two positions and to allow such disconnection to take place whenthe occupies its other position. herein shown as its rearward position.

A preferred embodiment of the in ention as applied to a machine of thetype specifi Cally mentioned above will now be described with the aid ofthe accompanyine' drawings. It is to be understood. however that theinvention could be applied to other lastii or ll ma hines and that itcould be em bodied in a variety of forms without departing from thespirit of the inv ntion.

In order to e l and allow the driver ;.se thedetent i to be ope ated the shaft extents 'hroigh the bearing 2% formedon the carer l0 and to the shaft secured the 18.

a X. oreinentioned arm The is proposition the shaft 22 of the detentmove forward with the carrier but th hook 26 will be held againstforward motion and thus the detent 14 will be caused to turn in thebearing 24 against the action of its spring 16 and will then be movedout of the recess 20 in the driver bar 6 so that the said bar will beallowed to be moved by the action of its spring 21 to drive a tack. Onthe other hand it will be understood that when the hook 28 is not inengagement with the hook 26, see Fig. 1, and the carrier is swung aboutits pivot, the said detent will swing bodily with the carrier and driverbar and its end will be retained in the recess 20 in the driver bar 6 byits spring 16 and consequently the said bar will be held againstmovement so that it will not drive a tack.

When one of the tack drivers is not in operation, of course the supplyof tacks to that driver will be discontinued. One mechanism forefiecting this is disclosed in the above mentioned patent to Bates.

In order to lift the hook 28 out of engagement with the hook 26 so as toprevent the operation of the driver bar 6 the arm 30 is operativelyconnected through a rod 36 to a lever 34 pivoted at 47 which moves thethick edge gage 9 into and out of operative position through aconnection 23, so that when the edge gage is in its forward position itwill, if so allowed, through its operative connections, yieldingly liftthe hooked arm 30, as shown in Fig. 1.

In order to carry this into effect the rod 36, which slides throughbearings 88, &0 on the frame of the machine, has at its upper end a boss42 from which projects an arm 44, Fig. 2, engaging ina recess 31. Fig.3, formed in the arm 30. The rod 36 is adapted to be engaged at itslower end by the face of a wedge 46 yieldingly supported by a spring 48and carried in a boss 50 on the edge gage actuating lever 3st. Wi'ththis arrangement. when the lever 34; is turned to move the edge gageinto contact with the wedge 4E6, it will, provided, as before mentioned,the plaiting mechanism has been thrown into operation, move the rod 36up wardly and will raise the hook 28 out of engagement with the hook 26.lVhen the lever 3% is moved in the other direction the arm 30 and itshook 28 will be moved downwardly by a spring 54: which is attached tothe arm 30 and to the bearing 38 and thus the hook 28 will be moved intoa position to be engaged by the hook 26 when the carrier is swungbackwardly.

In order', however, to prevent the arm 30 from being lifted exceptduring the plaiting operation the arm is also operatively connected tothe bell-crank lever which is provided to throw into operation the saidplaiting mechanism. This is effected by an inverted U-shaped lever 56mounted to turn on the pin 32 on which the arm 30 is mounted. The lever56 has a cam 58 formed on its end remote from the pivot 32. The lever isacted on by a spring 60 which is secured thereto and to the frame of themachine and this spring is adapted to swing the cam 58 downwardly andhold it in contact with a roller 62 which is operatively connected tothe means for throwing into operation the plaiting mechanism. TheU-shaped lever 56 is secured to a sleeve 64 which surrounds the pin 32and which is provided With a pro jecting arm 66 carrying a stop 68 whichoverlies the arm 30, Fig.

The means for throwing the plaiting mechanism into operation and whichcontrol the direction and extent of the plaiting movement of the pincers25 are substantially the same as those described in the specification ofprior Patent No. 584,7 4 previously referred to, and comprise an arm 70which is journaled upon a stud 72 mounted in lugs projecting from themachine frame. The arm 70 is provided with a bearing 76 in which a stud7 8, Fig. 2, is journaled, the stud having a bearing 80 secured to itsupper end. The bearing 80 receives an extension 82 of one of two studs84 that form the connections between bifurcated arms 86 of a bellcranklever 88 and a collar 90 on a shaft 92 which the arms embrace. The stud78 and extension 82 are arranged with their axes at right angles toone-another and are capable of sliding in their respective bearings soas to compensate for the curved paths of movement of the arm 70 and theforked arm of the bell-crank lever 88.

The collar 90 is arranged to slide upon a shaft 92 and is thereby causedto control the direction and the extent of the plaiting movement of thepincers in the known mannor. The bell-crank lever 88 is pivoted at 9%and is operated through a link 6 from the usual knee lever which is notshown. To efiect the sliding of the collar the arms 86 carry plates 98which are pivoted to them by the studs 84, one of which is extended at82- aforesaid to effect the connection with the arm 70 as previously setforth. The roller 62 is mounted on a pin 10% carried by one of theplates 98, see Fig. 4c.

The cam 58 on the U-shaped lever 56, is so arranged that when thebell-crank lever 88 is rocked about its pivot to throw the plaitingmechanism out of operation the roller 62 will engage the cam 58 and willswing the lever 56 about its pivot 32 against the action of the spring60 and will move the stop 68 on the projecting arm 66 into such aposition that the arm 30 cannot be lifted, see Fig. 3. 7

If, on the other hand, the lever 88 is rocked so as to throw theplaiting mechanism into operation the roller 62 will be moved off thecam 58 and the U-shaped lever will be turned by its spring 60 into adirection such. that the stop 68 will lie moved away from the arm 30 sothat if the edge gage is then moved forward the arm can be lifted throngthe upward pressure of the arm 44;.

through the connection push the lever 3e and wedge l6 rearwardly and thehook :48 will be moved downwardly ll-y its spring so that when thetacker carrier is swun lmckwardly the hook 26 will engage th hook 2S andduring the next forward swin of the tack carrier the detent 1% will bemoved out of engagement with the recess 20 and the driver bar will befree to be driven its spring.

Should the edge gage be moved forward for any purpose hen the plaitingmechanism is not in operation, this forward movement of the edge beingpermitted by reason of the fact that the wedge d6 is yieldinglysupported, the hooked arm will not be lifted by reason of the stop 68 onthe lever 56. Also should the edge gage be left forward when theplaiting mechanism is thrown out of operation the stop 68, as the lever56 is s rung by the roller engaging the cam 58, will contact with thearm 30 and force it downwardly so that it can engage the hook on thedetent. It will thus be understood, that, while it is possible to drivetwo tacks during the plaiting op :ation when the edge gage is back orwhen the plaiting mecha ism is out of operation and the edge is forward,yet if the edge is forwa rd and the plaiting mechanism is in operationthen only one tack be driven.

The cam 58 on the ll-s aped lever is constituted b a rib projecting froma plate, the said rib extending centrally across the said plate. iViththis arrangement the said cam will be engaged by the roller whether thebell-crank lever is rocked so as to cause the plaiting mechanism toplait from left to right or from right to left. During the plaitingoperation the roller is in contact with the said plate and is located onone or the other side of the rib according as to whether the plaiting isfrom left to right or from right to left.
